Summary:

AbstractThe engine efficacies require the blend of friction reduction approach for optimising the attained output. The research elucidates the scope of friction reduction mechanism to increase engine power and life. The engine components piston and piston rings are coated with the unique composite of graphite, molybdenum disulfide, tantalum layer to reduce friction and wear. The coating on piston minimizes direct contact between piston and cylinder liner, which reduces friction, BSFC and lead to better thermal stability, and engine life. The research also focuses on friction reduction of camshaft bearing by replacing sliding contact bearing with low friction roller bearing. The friction between engine components reduces output power, and the engine oil temperature plays a significant role in it. The research empowers zirconium dioxide coating on oil sump in order to reduce the temperature decay rate so that the optimized engine oil temperature of 100°C can be retained for longer time. The cars because of traffic gets on and off sporadically, where engine oil temperature role become more prominent, as optimised temperature reduces the problems caused by cooler engine oil temperature which is more viscous and absorbs chamber warmup temperature. The absorption of chamber temperature leads to extra combustion affecting BSFC. The variable flow of oil according to engine RPM reduces oil pump friction by and BSFC by significant amount. The use of lightweight ceramic and sheet metal material in valve train reduces FMEP by 38%. The effect of different engine oils grading on friction have been elucidated on the basis of kinematic viscosity and viscosity index
